I have been using heptahydrated magnesium sulphate MgSO4.7H2O, which states MgO 16% and SO3 32%, giving us the approximate 10% mg (I think).
Now I got my hands on some magnesium sulphate which states MgO 23% and SO3 45% - I guess it is the "dry" salt.
Simple math tells me to use from this "dry salt" two thirds of the quantity I use from the heptahidrate version.
Is this correct?
Thank you for any validation or correction.
